PHOENIX – Perhaps Mike Piazza should be the Mets’ hitting coach. His team can hit, too.

Piazza, Italy’s hitting coach, blasted the most home runs for a catcher in major league history with 396 and Team Italy blasted Team Canada, 14-4, today at Chase Field to move to 2-0 in the first round of the WBC, virtually assuring the Italians a trip to South Beach and Round 2 of the tournament.

Team Italy beat Mexico on Thursday night and came back to rout Canada, drilling 17 hits in the process of the mercy rule win.

Piazza told the Post in mid-November that Team Italy was no pushover after having won two European Championships. The Italians came here with a point to prove.

“I’ll take none of the credit and none of the blame, that was my motto when I was catching,’’ Piazza told the Post with a smile. “I love this tournament and we picked good guys and they’ve really meshed with the Italian guys. We realize how difficult this is going to be but we’re having fun, we’ve done our homework and we just have to execute.’’

Piazza said he has been getting a lot of congratulatory texts. “My favorites are the ones in Italian,’’ he said. “This is great for the tournament,’’ he added. “We want to continue to grow baseball in Italy.’’
